Honest Abe's Guide to Presidential Elections, by Jack Silbert, informs readers about the US election process. It's written from the point of view of Abraham Lincoln, and covers most everything a teacher would cover, with a bit of humor thrown in. It is written in clear and understandable language that would be a good fit for third through fifth or sixth graders. It has fun cartoon illustrations and a glossary of terms.
Honest Abe's Guide to Presidential Elections is a great book to use during a civics discussion or around election time. Students could use what they learn from it to hold a mock presidential election in the classroom. It also provides great topics for debates and essays.
